CVE-2025-71141

/// Technical description

In the Linux kernel, the following vulnerability has been resolved:

drm/tilcdc: Fix removal actions in case of failed probe

The drm_kms_helper_poll_fini() and drm_atomic_helper_shutdown() helpers

should only be called when the device has been successfully registered.

Currently, these functions are called unconditionally in tilcdc_fini(),

which causes warnings during probe deferral scenarios.
